The Dallara T12 or Dallara FR35-12 is a racing car developed by Italian manufacturer Dallara for use in the World Series Formula V8 3.5, a series originally formed from the World Series by Renault top category. The T12 is the third generation of car used by the World Series by Renault/WS Formula V8 3.5, and was introduced at Silverstone on August 24, 2011.{{cite news|title=New Formula Renault 3.5 unveiled at Silverstone|work=renault-sport.com|publisher=Renault Sport|url=http://www.renault-sport.com/en/racing/fr_35/news.php?news=152136.html|date=20 August 2011|accessdate=24 August 2011}}{{dead link|date=September 2017 |bot=InternetArchiveBot |fix-attempted=yes }}

The T12 chassis featured a new, {{convert|530|bhp|kW|abbr=on}} V8 engine supplied by British firm Zytek Motorsport and designated as ZRS03.
